This site provides a set of different tools which may help you to test your privacy settings or to resolve some network problems. Even though first versions of some tools were written years ago, they are still useful and I hope they may be of use for you too.
Please be advised that some of the scripts are in "beta", so you may want to check leader.ru server for old stable versions. Also bear in mind that some tools may be unavailable for you if your IP address is changing during the browsing of this site. Some specific tests, such as port scans, are not going to be available if your connection appears to be going through a proxy.
